应用

PEG-SS-PCL is a redox responsive, biocompatible, amphiphilic block copolymer composed of a hydrophilic poly(ethylene glycol) (PEG) block and a hydrophobic poly(ε-caprolactone) (PCL) block, with a reducible disulfide linkage between blocks. This polymer can be fabricated into Glutathione (GSH) responsive nanoparticles which can be used as an intracellular drug delivery system.

The lack of efficient therapeutic options for many severe disorders including cancer spurs demand for improved drug delivery technologies. Nanoscale drug delivery systems based on poly(ethylene glycol)-poly(ε-caprolactone) copolymers (PEG-PCL) represent a strategy to implement therapies with enhanced drug accumulation at
